When was the last time the Houston Astros won back to back 4-game series?

Question

The Astros swept the Reds in a 4 game series in Cincinnati earlier this week, and have now won the first 3 of the 4 game series against the San Francisco Giants in Minute Maid Park. My question is when was the last time the Astros have swept back to back 4-game series?

Answer 1

idk

Answer 2

This is the first time in Franchise history the Astros have sweep back to back 4 game series.  Pretty impressive!  Its not going to matter though, they still won't make the wild card.  Make next year!

Answer 3

I have no clue. Maybe u wont have to worry about that is it will prob happen tomorrow. Houston has won 7 straight. Impressive.
